One button gives access to the thermal settings:
                - External fluid temperature
- Cooling circuit fluid temperature
Note: The external fluid temperature corresponds to the
                temperature of the fluid surrounding the machine. It is also considered as the
                temperature at the “infinite” for the computation of radiation from the frame to the
                infinite.
Note: The cooling circuit fluid temperature
                exists only when a cooling circuit has been added by the user in the design
                environment. In this case, this input describes its fluid inlet temperature.
